Add a new type of profile data in ART profiler

This CL allows the ART profiler to collect bounded stack information
that contains only method signature and dex pc on the current stack
frames to a bounded depth. The type of the profile data is by
default disabled, and can be enabled by setting the option
"-Xprofile-type:stack". The bound is controlled by the option
"-Xprofile-max-stack-depth:integervalue".
